Answer:
D) K being transported out of the guard cell.
Explanation:
The movement of water in the terrestrial plants is a very important factor as each cell of the plant require water to survive.
The movement of water is influenced by many physical, chemical and process going on in the plants like transpiration and stomatal opening and closing.
Water posses adhesion and cohesion properties which allow the water molecules to form a bond with other surface and with each other respectively. This allows the movement of water in the xylem by a process called capillary action.
The evaporation of water creates a pressure on the plant to absorb water from the soil but when potassium ions move out of the guard cell of stomata, the guard cells lose turgidity and stomata gets closed.
Thus, Option-D is correct.
Answer:
Few, if any aquatic organisms will be able to survive in these regions, they will become dead zones
The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
Answer:. A novel fungal infection could spread to colonies and cause dramatic population crashes, as seen in the comparative study
Explanation:
fungal diseases of wildlife, amphibian chytridiomycosis and bat white-nose syndrome are diseases in bat that have emerged rapidly and unexpectedly over the past several decades.
These diseases have lead to unprecedented local and global decrease in population of amphibian and bat species the infection colonize their territory and pose serious threats to biodiversity and ecosystem stability due to loss of many of them.
